Abstract

Destruction of atrial tissue by radiofrequency ablation for preventing relapses of atrial fibrillation carries a risk of rare but frequently fatal fistula formation between the atrium and the oesophagus. Early symptoms include ischaemic disorders and gastrointestinal bleeding occurring within two weeks following the procedure.
